蔚来ES6前空气悬架设计
摘要
汽车作为人类日常必须的交通工具，其可操纵性、舒适性一直是驾驶者以及工程师的奋斗目标，为了在不影响操纵性又提高驾驶舒适性的前提下，空气悬架应运而生。空气悬架通过调节空气弹簧的充气度进而改变悬架软硬度，以此来提高汽车行驶平顺性、操纵稳定性、增加舒适感。现今电控空气悬架在汽车上的应用越来越广泛，也逐渐成为了民众购车参考的指标之一。对此研究有效的、智能的、可控的、安全的空气悬架对发展空气悬架系统的应用具有重要意义。
本文本次设计是对汽车空气悬架在行驶途中振动而进行的结构改进，设计出结构简单、结实耐用、符合轻量化标准、体积适中的空气弹簧悬架，该悬架的设计不仅能够应对中国地形、符合中国道路情况，还可以提高驾驶人驾驶愉悦感。疫情期间利用互联网学习悬架有关知识，以蔚来ES6为研究目标，根据整车结构及参数计算悬架设计所需的各类参数。设计空气弹簧的布置结构；悬架减震器的计算选择等。使其符合国家相关规定，满足设计要求和使用需求。

Design of Front Air Suspension of Weilai ES6
Abstract
As a necessary means of transportation for human beings, the maneuverability and comfort of automobiles have always been the goal of drivers and engineers. In order to improve the driving comfort without affecting the maneuverability, air suspension came into being. The air suspension changes the soft hardness of the suspension by adjusting the inflation degree of the air spring, so as to improve the vehicle ride comfort, handling stability and comfort. Nowadays, the electronic control air suspension is more and more widely used in automobiles, and has gradually become one of the reference indicators for people to purchase automobiles. The research on effective, intelligent, controllable and safe air suspension is of great significance to the development of the application of air suspension system.
This graduation design is a structural improvement to the vibration of the automobile air suspension during driving. The design of the air spring suspension is simple in structure, strong and durable, meets the light weight standard, and has moderate volume. The design of the suspension can not only cope with the Chinese terrain and meet the Chinese road conditions, but also improve the driver's driving pleasure. During the epidemic period, the Internet was used to learn about suspension. With Weilai ES6 as the research target, various parameters needed for suspension design were calculated according to the structure and parameters of the whole vehicle. Design the arrangement structure of air spring; Calculation and selection of suspension shock absorber, etc. Make it conform to the relevant national regulations and meet the design requirements
